Thabiso Tema, POWER BREAKFAST host, speaks to Prof Bruce Mellado – Professor of Physics at Wits University who runs an air quality monitoring programme across Gauteng, about how Johannesburg residents have raised concerns after a strong sulphur odour, often compared to the smell of rotten eggs, spread across parts of the city. The smell has triggered widespread reports of headaches, chest tightness, fatigue, and respiratory discomfort. The latest surge in air pollution has prompted public frustration over the recurring nature of the problem and its impact on residents’ daily well-being.
